FURNACEJIILE.

To all whom it may-concern:

Be it known that I, EDWARD CpiMiEIER, a citizen of the United States, residing at Phoenixville, in the county .of Chester and State of Pennsylvania, have invented certain new and useful Improvements in Furnace-Tile, of which the following is a speci fication.

My invention relates to improvements in furnace tile, and amore particularlyto an improved cast iron tile having an inclined groove therein adapted to direct the steam from a soot blower inserted through a stay tube in the box header into the groove formed in the baflling tile supported'on the boiler tube.

In the arrangement of bafiiing tile on boiler tubes, it frequently happens that such tile are so disposed that a soot blower directed through a stay tube will be out of alinement with the upper or grooved face of the tile, and in such case my improved metal tile is used and operates as a deflector or inclined trough to properly direct the steam into the groove of the baffling tile.

A further object is to provide a metal tile use in connection with my improved grooved bafiling tile, and which is so arranged that the inclined groove in the metal tile registers with the groove in the bathing tile, and-insures a proper direction of the steam for With these and other objects in view, the invention consists in certain novel features of construction and combinations and arrangements of parts as will'be more fully hereinafter described and pointed out in the claims.

In the accompanying drawings: Figure 1 is a fragmentary view in vertical longitudinal section illustrating my improvements. Fig. 2 is a fragmentary view in section on the line 2-2 of Fig. 1, my improved metal tile being shown in end elevation. Fig. 3 is an enlarged fragmentary plan View showing the box and the other parts in elevation.

1 represents a steam drum of the boiler which communicates and is supported by a box header 2, the latter communicating with boiler tubes 3, and provided with stay tubes.

10. The construction above described is a common type of boiler, and I would have it understood that my present invention is Specification of Letters Patent.

not limited to any particuler construction of boiler, and may be used with various types.

On the boiler tubes 8, battling tile 4 are supported, and these baffling tile are preferably of burnt fire brick or clay, and are provided intheir upper faces with longitudinal grooves 5 constituting a repository for soot which accumulates therein. These tile 5 I term baffling tile to distinguish them from my improved metal tile 6, although the latter operates as a baffling tile. This tile 6, as above stated, is preferablyof cast iron, and is provided at its sides with curved faces 7, which rest against and are supported by the boiler tubes 3. The tile 6 inclines upwardly from its outer to its inner end, and is of general trough shape throughout, the upper end of the tile 6 registering with the grooved surface 5 of tile 4, while the lower end of the tile 6 is located in a plane below the stay tube through which the soot blower (not shown) directs the steam to blow out the soot which is deposited in the groove 5 of the tile.

The stay tube 10 is up-set or flared outwardly at its ends as shown at 8, and the tile 6 at one end is recessed as shown at 9 to accommodate the end 8 of tube 10 and allow the tile 6 to lie snugly against the header 2.

With my improvements it will be noted that when the blower is directed through the tube 4, the steam will be directed through the tile 6 into the groove 5 of tile 4, and it will also be noted that the tile 6 has its groove v11 widest at its end adjacent the tube 10 and gradually decreases in width to its other end where it conforms in width to the width of the groove 5, so that the tile 6 not only tapers upwardly from one end to the other, but its groove or trough 11 decreases in width from its-inlet to its outlet end, hence the steam is more or less confined, and the tile operates to a certain extent as a nozzle to direct the steam through the groove 5. Y

Various slight changes might be made in the general form and arrangement of parts described without departing from my invention, and hence I do not limit myself to the precise details set forth, but consider myself at liberty to make such changes and alterations as fairly fall within the spirit and scope of the appended claims.

Having, thus described my #invention,"

What I claim as new and desire to secure by Letters Patent is:

1. The combination With a boiler having a box header, stay tubes in the header, and boiler tubes secured to the header, of bafiiing tile supported on the-boiler tubes and hav 7 ring longitudinal grooves in their upper faces, and a metal tile supported on the boiler tubes secured to the header, of baf- Copies of this patent may be obtained for I name to this specification in fling tile supported on boiler tubes and havinglongitudinal grooves in their upper faces, a metal tile supported on theboiler tubes "and having an inclined groove in its upper face, the lower endof said groove located in a plane below the, stay tube',and the upper end of said groove registering With the groove in the firstmentioned tile,

said'meta'l tile having "a recess in one end receiving the end of the stay tube therein, substantially as described.

In testimony whereof Ihave signed my of tWo subscribing Witnesses.
